rtcRetainBuffer(3)

💖 rtcRetainBuffer(3) — bestie edition 💖

ok so this is a page from the Embree Ray Tracing Kernels 3 manual, and today's main character is rtcRetainBuffer. it's giving ✨ownership✨, it's giving 🌸reference counting🌸, and honestly? it's a short one. let's go 🫶

---

✨ NAME ✨

rtcRetainBuffer — increments the buffer reference count 💅

---

✨ SYNOPSIS ✨

#include <embree3/rtcore.h>

void rtcRetainBuffer(RTCBuffer buffer);

like, that's it. that's the whole signature. no cap 🎀

---

✨ DESCRIPTION ✨

so here's the tea ☕: buffer objects are reference counted. every buffer is keeping track of how many people are holding onto it, iykyk.

the rtcRetainBuffer function increments the reference count of the buffer object you pass in (that's the buffer argument, bestie — don't forget to hand it over 👑).

and the reason this is iconic? because rtcRetainBuffer, working together with rtcReleaseBuffer, lets you use the internal reference counting inside a C++ wrapper class to handle the ownership of the object. literally the dream team 🤝

---

✨ EXIT STATUS ✨

if something goes wrong (😭), an error code is set, and you can go query it using rtcGetDeviceError. so like, vibe check your errors, fr fr.

---

✨ SEE ALSO ✨

• [rtcNewBuffer]
• [rtcReleaseBuffer]

---

okay bestie real talk: retain and release are a matched set. if you retain, you release. that's the whole personality of reference counting 🦋

---

that's the whole page!! 🌈 no filler, all signal. this was rtcRetainBuffer(3) from the Embree Ray Tracing Kernels 3 manual, and that's a wrap — slay, hydrate, and remember to decrement your reference counts 💖✨🎀🫶
